How to Count Valence Electrons for Lewis Structures
1. Count each atom's valence electrons
2. Add electrons for negative charge
3. Subtract electrons for positive charge
4. Place bonding pairs between atoms
5. Fill outer atoms to octet first
6. Put remaining electrons on central atom
7. Use double or triple bonds
Common Lewis Structure Mistakes
1. Forgetting to adjust for overall charge
2. Giving hydrogen more than two electrons
3. Leaving central atom electron-deficient
